Another thought, not sure on what the TSX vacuum and PCV system looks like, but if somehow oily water vapour is freezing in the vacuum lines, then it could temporarily block vacuum assist until it melts.
Yeh that's more likely that some vapor froze up the vacuum line and killed the assist.

Then the question is does the OP even lift (squat)?

Time to redo the brake fluid change before temp gets even lower to -20C. After that, I would look into getting the master brake cylinder repaired or changed.

Hopefully my repair bill won't be too high tomorrow...

Back to my car after work. Started the engine and depressed the brake pedal numerous times. On the first few steps the pedal could be fully depressed. THEN the pedal became hard to depress!!

I then stepped on it few more times and the pedal could be fully depressed...

This is bad...

It's either your brake booster or you have a failing check valve.

..... you have a failing check valve.
+1 Seems to be a known problem in some Acuras with the valve freezing shut


... CUSTOMER STATES THAT ON A COLD START AT ANY TEMP UNDER 10F DEGREES THE BRAKE PEDAL IS ROCK SOLID AND CAN NOT BE MOVED AT ALL UNTIL THE VEHICLE REACHES OPERATING TEMP AND IF THE VEHICLE IS GARAGE KEPT AT AROUND 25F DEGREES IT WILL NOT DO THIS.

The service tech said my brake fluid needs changing...brake valve is fine. Hopefully this would be it.

Pump the brakes on a back road before driving at high speeds. Give time for brakes to warm up and make sure they work.

Hondas are not what they used to be...
My car is only about 5 yrs. old and certainly didn't expect to have issue like this...very disappointing...

This is not the issue unless your sealed system is full of water. There is moisture getting on the check valve which then freezes and cause your symptoms. If this cold weather persists you will experience it again. Get them to at least disperse the mositure on the check valve.

Or they didn't properly bleed the lines and there's trapped air bubbles.
LOL what? So two years ago the fluid was flushed and now the air bubbles are appearing? :lol:

Not to mention the fact that air in a brake system will cause a squishy or long pedal or cause the pedal to sink to the floor w/o appropriate braking action, not the opposite.

I really have a hard time posting on here with all the nonsense, I well-remember now why I originally stopped posting on this subforum for so long.

A firm pedal typically points to vacuum/booster failure/lack of assist, not air in the lines. I dunno what people are thinking here sometimes.

Surely a catch can would be the solution though eh? :lol: I mean I hate it to have to be this same poster but c'mon people that don't understand basic hydraulics (or seemingly much about technical and mechanical aspects of automobiles), surely they should be trusted to know enough to post about the intricacies of the combustion process I guess? Not sure what else to do but SMH. RFD's Automotive section ends up looking ridiculous not because of differing opinions )which are fully expected on a forum) but because of people that, from all evidence, have absolutely no idea what they are on about and open their mouths anyway :rolleyes: in regards to matters of fact and science.

As I've said many times I've gone skiing a bunch of times but you know what I haven't got the slightest clue about skis or bindings or any of that stuff because I'm no kind of skiing expert just because I've strapped some on, on occasion. So you don't see me going on a skiing forum going on about what the best bindings or waxes (or whatever the heck skiing people talk about) are. Why? Because I don't know anything about them! So why do we have people here that don't know a thing about cars, engines, and wouldn't know a pushrod from a connecting rod...and cleraly have no respect for science or objectivity come on here and spew a bunch of nonsense and then try to get into arguments about it like they do? C'mon this is basically just trolling and not the funny kind we get from guys like nasa25.

Anyway I'm sure from this particular poster we're now going to get all the reasons why air in brake lines...that was left there two years ago has somehow caused OP's problem of a stiff pedal and no braking action. With all the credentials of probably never having actually worked on a car ever...except perhaps to do expert installs of catch cans I guess.

Glad OP's brakes are at least working fine now.

Wow, a 1hr post and you still ended up looking stupid.
